JAM PUMPKINS

I've had a disaster! The marmellata pumpkin I grew to make some authentic Italian marmellta has exploded on me!!!!  It's really soft so I assume it's no good

What I want to know is, what other pumpkin or squash could I use to make my jam. I've got loads of  Crown Prince and some of those small lantern making jobs

I'm desolate about it as I'd assembled all my jars, and even Grappa 

Anyone?

some are better than others, it's horses for courses and I didn't want to get all my gear ready and use the wrong pumpkin and it turn out rubbish 

I thought someone on here would know for definite which are best to use
